GRAIN-METER.

Specification of Letters Patent.

Patented Ma.y 4, 1909:

Application filed July 22, 1908. Seria1 No.. 4 44,80Zl

To all whom 'it may concern:

Be it known that I, WILLIAM Ross, a citizen of the United Sates, residing at Louisville, in the county of Jefierson and State of Kentucky, have invented a new and useful Grain-Meter, of which the following is a.

specification.

This invention relates to grain meters and has for-its object to rovide a comparatively simple and thorougiily efficient machine of this character especially designed for meas uring seed, grain and other material. and discharging the same into suitable bags or re-' ing shaft of the machine and. provider with fingers adapted to enter the several compartments for simultaneously varying the capacity of all of said pockets and rendering the same of uniform slze.

Further objects and advantages will .appear-in the following description, it being understood that various changes in form,

proportions and minor details of construe? tion may be resorted-to with-in thescope of the appended claims.

In t e accompanying drawings forming-a part of this specification: Figure 1 isa pers ective view of a combined measuringand filling device constructed inaccordance with my invention. Fig- 2 is a rear elevation of the same. Fig. 3 is a pers ective view of the rotary ,cylinder and gage etached.

Similar numerals of reference indicate core responding parts in all of the figures of the drawings."

The Improved machine forming the sub ject matter of the-present invention includes a casing. 5 having a cylindrical-bore 6) and provided with a hopper 7 and dlscharge spout-8 communicating with the bore,-'-as own.

Extending laterally from one side of the casing-5 are s ced ears-:or lugs-9 ada ted to embrace a ta le-top or-other sultab e-support, the lower lug being provided with a ver-v tical perforation for the reception of a screw or similar fastening device 10, by means of which the casing may be held in position on the support.

Mounted a cylinder 11 havinga plurality of radiating pockets or compartments 12- formed therein for the reception of the grain, seed or other material to be'measured, said pockets tel?- for rotation within the bore 6 is minatingshort on one end of the cylinder to form a flange 13.

Extending longitudinally of the cylinder 11 and keyed orother-Wise .rigidly secured thereto is an operating shaft. 14 on which is slidably mounted'a gage 15'.

The gage 15 is provided with a plurality of. longitudinally disposed fingers 16 of; the same shape as the pockets12 andadapted toenter the latter for regulating the capaeity of said pockets, thereby to permit the discharge I of any desired quantity of grain.

Threaded in an opening-in thecylindrical gage member 15 is a clamping screw-17', the

inner end of which is adapted to bear against the-operatingshaft 14v for clamping thegage in adjusted position.

Slidably mounted on the forward end. of

the cylinder 11 are a plurality of stoplplates 18 adapted to bear against the front face of the .casing 5 and prevent rearward :movement of-the cylinder 11 within the'bore' of. the-casing. I

The plates 18; are provided with elongated slots 19: for the reception ofclamping Screws 20; which .latterextend throughut ie slots and engage the cylinder 1 1 sothat by loosening the screws 20. the plates may be retracted or moved in the direction of the operating shaft 14 to permit the withdrawal of the-.oyL inder 11 from withinthe casing.

Secured toor formed integral with the pe ripheral edge of the flange 13 area seriesof radiating finger pieces orpins-21 which by engagementwith the. casing form stepstto prevent the withdrawal of the cyhnder -11:

throu h the front portion of the.casing, jsaid pins a so serving as fingpr pieces by means \Qf which the device may e operated manually if desired? The rear faceof the casing; 5 is -out away at 22, and: riveted or otherwise rigidly secured to the-casing at said cut awayportion is one end of a flat spring23, vthefree end of which isinclined pr beveled and extendedwinxlthe If desired, a wheel or pulley 24 may be secured at one end of the operating shaft 14 with an en ine or ot operating the device.

"pockets being disc and connected through the medium of a belt er source of power for In operation, seed,grain or other material is introduced into' the hopper 7 and enters the pockets -12- as the latter successively register with the hopper, the material in said arged through the spout 8 into a bag or package when the pockets register with the spout.

In order to regulate the capacity of the compartments 12 it is merely necessary to release the adjustin screw 17 and slide the gage 15 lon'gitudina yet the operatingshaft 14 and subsequently tighten the-screw 17; as

will be readily understood.

\ By loosening the screws 20 andforcing the l plates inwardly in the direction of the oper-v ating'shaft 14 the-outer ends of said lates will clear the casin 5 so as to permit t e re moval of the cylin er 5 and gage 15 through the rear face of said casing.

.It will of course be understood that as many pockets may be formed in the cylinder 11 as is found desirable or necessary, .an additional pin 21 being placed on the cylinder for each additional'compartmentpr pocket. It will also be understood that the machines may be built in different sizes to accommodate different materials and that the cylin-' der 11 and casin 5 will be so constructed as to prevent crus g of the ,seed or grain when the machine is in operation. 1
